Patent DE-4206647-A1 (DE)
Inventor: SWIDERSKY HANS-WALTER
IPC: B09B3/00
Filed: 1992-03-03
Abstract: Acetylene compressed-gas cylinders contain an asbestos-containing carrier matrix. This matrix serves as a carrier for acetone which acts as a solvent for the acetylene (C2H2). Hitherto it has not been possible to dispose in an environmentally safe manner of compressed-gas cylinders which can no longer be refilled. The invention overcomes this problem by decomposing the asbestos-containing carrier material with an inorganic acid containing fluorine or a corresponding salt of such an acid.

Patent DE-4234513-A1 (DE)
Inventor: LIPP ROLAND DR
IPC: B65D77/38
Filed: 1992-10-13
Abstract: A container consists of a lid (2) and of a lower part (1) of which one or both are produced from a deep-drawable foil. Lid and lower part may be mechanically coupled to each other by means of a mechanical closure zone (21) and may be at the same time hermetically sealed to each other by means of an independent sealing zone (20) radially offset outwards. The arrangement is designed in such a way that once the sealing zone is undone for the first time the lid (2) may be used for closing again the container by means of the mechanical closure zone (21). The sealing material used to produce the sealing zone does not form a sealing layer of the foil, but is integrated or embedded in a foil matrix material (9) and is exuded out onto the contact surface during sealing in order to form a sealing film.

Patent DE-4309218-A1 (DE)
Inventor: ALLISON JOSEPH MICHAEL
IPC: H02M3/155
Filed: 1993-03-23
Abstract: A boost converter 24, provides warm-up and steady state run signals to the lamp 20 in a voltage fed manner over a coupling circuit using components of reduced size relative to conventional ballasts. Converter 24 has a switching transistor (Q1), (Fig. 2), controlled by a PWM circuit 28 responsive to lamp current and voltage and also operable to disable the converter 24 if excess current flows through the transistor. The output of converter 24 is coupled across a capacitor (C27), (Fig. 7), in series with the secondary winding of an output transformer (T102) of a lamp starter circuit 16 which generates high voltage starting pulses by discharging capacitors (C25), (C26) via a spark gap (E101) into the transformer primary. The capacitors (C25), (C26) can be recharged in about 6 milliseconds by a second converter circuit in order to allow a repeated start attempt to be made rapidly after a failed start attempt. The starter is disabled by a fault/timer circuit 26 if the lamp does not strike within a predetermined time. Circuit 26 also turns off the converter 24 if a high open circuit voltage is sensed. Converter 24 provides an initial warm up current of 6 amps decreasing exponentially to a steady state current of 1.2 amps. If lamp operation is interrupted for a short period a time-out circuit 30 is effective on restart to reduce the initial warm up current and the warm up period as a function of the interruption duration. In response to a fall in the DC input voltage, a fade circuit 32 causes the input current to be clamped to a constant value rather than the ballast being allowed to increase current in an attempt to maintain constant light output. The resulting dimmed lamp state is indicative of the voltage drop. If the input voltage falls further a lock-out circuit 34 disables the ballast until the input voltage has been restored to its nominal value. <IMAGE>
Patent DE-4312719-A1 (DE)
Title: Indexable carbide insert
Inventor: BASTECK ANDREAS DR
IPC: B23B27/14
Filed: 1993-04-20
Abstract: In known indexable inserts the mechanically resistant material is worn down too quickly, because it is exposed to stresses more in the sense of point stresses rather than surface stresses. In addition, the undisturbed cutting-edge form only remains on very short sections. The chips do not break as desired and the overall geometry is at an optimum only in a relatively narrow range of feed speeds. The cutting forces are relatively high; in particular, they change in the direction of higher cutting forces in the course of time. The invention attempts to improve this and this is done by the intermediate areas between the depressions being provided with a smaller gradient than the depressions. By the end of the intermediate area being put in front of the end of the base area of the depressions, the end of the intermediate area essentially deflects the chip, which can be deflected there over a large area (Fig. 5). <IMAGE>
Patent DE-4316091-A1 (DE)
Title: Method and system components to determine the location of a subscriber in a communication system
Inventor: WILHELM MICHAEL DIPL ING
IPC: H04M3/42
Filed: 1993-05-13
Abstract: Technical problem: Before a call can be set up in communication systems with mobile subscribers (mobile radio, UPT), the current location of the called subscriber must be determined. State of the art: Each change of location of the subscriber is notified to the switching device, which stores this information (GSM), or each subscriber is searched for by the switching device in a specific pre-defined area which is identical for all subscribers. Underlying principle: The normal location area of a subscriber is known and the subscriber is searched for in this area. Example: The terminal (E) creates and maintains a location profile of the assigned subscriber. This location profile is notified to a mobile switching centre (MSC1) and the latter then searches for the subscriber in the event of a call request in the area specified in the location profile. Advantage: Lower signalling and computing cost. <IMAGE>

Patent DE-4321103-A1 (DE)
Title: Domestic appliance having an electronic display
Inventor: ZINKANN PETER DR
IPC: F25D29/00
Filed: 1993-06-25
Abstract: The invention relates to a domestic appliance which contains a microprocessor and an electronic display for specific parameters, such as the temperature in a refrigerator and/or freezer or the time in an electric cooker or microwave oven, for example. The problem on which the problem is based is to provide a display option which reduces the current consumption in a domestic appliance.   This has been achieved in that the active mode of the display device of the appliance can be manipulated via an additional switching device, in the sense of measures which reduce the current consumption. The parameters are displayed by means of switching processes which the user initiates by opening the door of the appliance. The display is ended by closing the door or by the timer of the appliance microprocessor controller which has been preprogrammed by the manufacturer or by the user.

Title: Galvanic button cell which is closed in a gas tight manner
Inventor: KILB MANFRED
IPC: H01M50/166
Filed: 1993-07-30
Abstract: A galvanic button cell which is closed in a gas tight manner and, in particular, a miniature button cell in the form of an alkaline accumulator, for example of a nickel-cadmium or nickel-hydride accumulator is described. The cell has a tub-shaped housing (1) which is made of metal and in which two electrodes (3, 4) are arranged. The electrodes are insulated from the housing (1) by a supporting ring (6). A metal cover (2), which is mounted on the upper edge (7) of the housing (1) in a gas tight manner, with the interposition of an insulating ring, closes the cell. The special feature is that a disc (9) which rests on the inside of the cover (2) is integrally formed on the upper edge of the supporting ring (6). Centrally, the cover has a cup-shaped hollow rivet (11) which is expediently formed by spot welding, passes through a central opening in the disc (9) and fixes the disc on the inside of the cover (2), to produce a seal, by flanging over. A large-area seal, which is stable over a long period and has long leakage paths is thus produced (Figure 1). <IMAGE>
